Side by side and accompanied by the Orchestre de Chambre de Wallonie, they offer a programme that reveals their musical rapport for the first time on disc, whether the repertory is Baroque, galant or Romantic. So, alongside Telemann’s Concerto in D minor for two chalumeaux and strings, we have Carl Stamitz’s Concerto no.4 for two clarinets, while Mendelssohn’s Konzertstücke nos. 1 & 2 are juxtaposed with duos by Telemann and C. P. E. Bach. Each work constitutes a calm dialogue in which words are replaced by notes, a touching testimony to two exceptional careers.
